Claims.

This invention relates to color printing of fabrics or like materialsand deals more particularly with means for applying designs of more thanone color to such materials.

The application of printed designs on cloth in two or more colorsheretofore entailed passing the cloth through a single stage machine asmany times as there were different colors in the design or making use ofa multi-stage machine so that the cloth would receive a different colorat each stage of said machine. It is obvious that the foregoing eitherentailed an expensive method or necessitated the use of expensive andspace consuming machines.

The present invention contemplates the provision of a single stagemachine wherein a plurality of colors may be applied to cloth during asingle passage of said cloth therethrough.

The invention, therefore, has for its primary object the provision of adevice adapted for easy installation and combination with existingsingle stage machines whereby two or more colors may be applied in theform of a design to a piece of cloth with a single pass of said cloththrough the machine. Y

The invention further contemplates a device of great flexibility of usewhereby the design spacings may be readily set as desired.

The structural features of the device herein contemplated also form amaterial part of this invention, stress being made on the manner inwhich the various color pigments are segregated to obviate inadvertentintermixing therebetween.

The foregoing objects, features and advantages and others which willbecome apparent, are realized in the device illustrated in theaccompanying drawings which form the basis for the following detailedspecification, it being understood that this disclosure is intended asexemplary only of the invention and capable of many changes in size,proportion, and arrangement.

In the drawings:

Fig. 1 is a transverse cross-sectional view of a pigment-applying deviceas contemplated herein, said device being shown in its relation to thedrum and pattern cylinder of a typical printing machine for theindicated purpose.

Fig. 2 is a fragmentary plan view of a toe plate used in the device.

Fig. 3 is a top plan view of one end of the device shown in' Fig. 1.

Fig. 4 is a side elevational view thereof with parts broken away.

Fig. 5 is a fragmentary detail sectional view as takensubstantially inthe plane of the line 5-5 v of Fig. 1. l

In that embodiment of the invention which is illustrated, a drum of atypical fabric or cloth printing machine is shown at II). A patterncylinder II is applied in tangential relation to the surface of the drumID, the cloth l2 being arranged to pass therebetween. The arrangement ofthese parts is quite typical and follows present practice.

The pigment-applying device preferably comprises the walls l3 and I4 soshaped as to form a trough-like structure provided with endwalls Hi.This structure may be of any suitable length in accordance with thewidth of the cloth to be printed. The walls I3 and I4 are first directedtoward each other as at I6 and I1 and then follow a substantially commondirection with their respective portions l8 and I9 to form a relativelynarrow downwardly directed opening 20.

Each wall l3 and It, as herein contemplated,

is provided with a series of preferably uniformly spaced grooves 2|arranged throughout the entire length of said walls, said groovespreferably following the contours of the wall portions l6, ll, [8 andI9.

Divider plates or partitions 22 are provided. These are shaped tosubstantially conform to the contours of the mentioned walls. Thesepartitions preferably project downwardly below the opening 20 as at 23for reasonslater apparent. The upper edge of said partitions arepreferably spaced from the .top edge of the trough to form apigment-receiving chamber 24.

A separating member in the form of a plate 25 is arranged longitudinallyupon the top of the partitions 22 and for the three color arrangementshown, is provided with openings 26, 21, and 28.

Arrangement is made to divide the chamber 24 into a plurality of panels.In this instance, two longitudinal divider members 29 and 30 are shown,said members dividing the chamber 24 into channels 3|, 32, 33. I

The end walls [5 are preferably grooved as at 34 to receive the ends ofthe divider walls 29 and 30, the latter being clamped in position as bymeans of clamp plates 35 and clamp screws 36 having seats in thementioned end walls.

In setting up the device the spacing between the design elements whichare arranged in lines is first determined. The partitions 22 are thenplaced in selected grooves 2 I, as best seen in Figs. 3 and 4, to formcompartments 31, 38, and 39.

A separator plate which has its openings 26, 21

and 28 so spaced as to accord with the spacing of the compartments, isthen selected and placed in the trough upon the partitions 22. Itwill benoted from Fig. 3 that the opening 26 of the plate 25 communicates thechannel 33 with the compartment 38. It is apparent then that pigmentplaced in the channel 33 can find its way only into the compartment 38through the mentioned opening 26. In a like manner, the channel 32 iscommunicated with the compartment 39 by means of the opening 21, and thechannel 3| is communicated with the compartment 31 through the opening28. It should be understood that there are several of each of theopenings 26, 21 and 28 all similarly arranged to those shown, tocommunicate their respective channels with desired compartments.

While a single partition 22 may be employed to separate adjacentcompartments, inaccuracies in manufacture dictate the use of two or moresuch partitions as shown to obviate the possibility of leakage of thepigment in one compartment to an adjacent compartment. A reasonabledegree of accuracy in fitting the separator plate 25 will insure againstleakage of pigment in the channels into undesired compartments.

After the plate 25 has been placed the longitudinal divider members 29and 30 are st in the selected grooves 34 formed in the end walls l5 andthe clamp plate 35 is slid into place in overstanding relation to theends of said walls and looked as by means of the bolts 36. Theadditional groove 34 shown in Figs. 1 and 3 is provided in the eventthat the trough is to be set up for two color application- In the latterevent. one of the walls 29 or 30 would be positioned in the groove 34 todivide the chamber 24 into two channels instead of the threeillustrated. Thus, provisions can be made to divide the chamber 24 intoany number of channels for as many colors as desired.

The pigment passing from the channels 3|, 32, and 33 to the respectivecompartments 3!, 39, and 38 pass downwardly through the opening 20. Atthis point, the pigment is guided to the pattern cylinder ll throughopenings or notches 40 formed in a toe plate 4|. The upper surface ofsaid plate is preferably grooved as at 42, said grooves being spaced toalign with the grooves 2| of the walls I 3 and 4. The mentionedprojections 23 of the partitions 22, set into certain of these groovesto form an effective seal against inadvertent seepage of pigment fromone compartment to an adjacent compartment. The toe plate 4| is made upin accordance with the spacing of the compartments so that the spacingbetween the notches 40 accords therewith. The pigment passing throughthe notches falls against the inner surface of the pattern cylinder,seeking its way through the pattern openings 43 thereof and onto thecloth l2 to be applied thereto as shown at 44.

The toe plate carries a doctor blade 45 which serves to close the frontof the notches 40 and has intimate contact with the inner surface of thepattern cylinder to prevent any pigment from seeping therebeyond. Thedoctor blade is preferably affixed to the toe plate 4| and the formerpreferably clamped to the wall portion l8 as by means of the clamp bar46, the spaced studs 41 and the thumb screws 48.

From the foregoing description it can be seen that a different coloredpigment may be plated in each of the channels 3|, 32, and 33; that thesepigments would then pass through the openings in the separator plate 25to the respective compartments 31, 39, and 38; and that the pigmentsfrom these compartments would be directed to the openings in the toeplate and thus to the pattern cylinder and the cloth I 2 to be appliedupon the latter.

The flexibility of use of the structure is apparent since the spacingincrements of the compartments may be varied at will, it being onlynecessary to provide a separator plate with holes spaced in accordancewith the spacing of the compartments and a toe plate with notchessimilarly spaced. Additional flexibility of use is imparted to thedevice by the means for permitting interchangeable positioning o'ffthedivider walls 29 and 30. These walls coupled with suitably arrangedslots 34 will permit setting up the device to provide a number ofpigment-receiving channels in accordance with the number of colorsthereof to be used.

The device is made readily applicable to and removable from a printingmachine, each end thereof being provided with bracket means such asshown at 50. These brackets may bremovab y supported on any desired partof the printing machine to facilitate ready removal of the device andalso of the pattern cylinder,

From the foregoing it can be seen that a simple and efficient device hasbeen provided for the purpose intended. Inasmuch as many changes inconstruction and arrangement may be made, the foregoing disclosure,while at present preferred, is intended merely to convey the portion ofsaid trough, a separating member be-- tween said compartments and saidchannels formed with openings communicating each channel with arespective set of compartments, and a toe plate secured to the troughand formed with openings communicating with said compartments forreceiving pigment from said compartments.
